IMPROVEMENT 11v STOVE-PIPES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern.-

Be it known that I, J osnrn W. Barns, of St. Paul, in the county ofRamsey, and in the State of M innesota, have invented certain new anduseful Improvements in Stove-Pipes; and do hereby declare that thefollowing is a full, clear, and exact description thereof,referencebeing had to the accompanying drawings, and re-the letters ofreference marked thereon.

This invention has for its object the converting of a horizontal draughtinto a perpendicular, or vice term.

The difficulty with the most of chimneys is, that the horizontal andperpendicular currents strike each other and cause a collision.

My improvement is so arranged, that when the two currents come together,they are going the same way,

thus helping the draught of both; and

It consists in so constructing the joint of the pipe that goes into thechimney, also in the T or connectionpipe, that such an object may beaccomplished.

In order to enable others skilled in the art to which my inventionappertains, to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, whichform a part of this specification, and in which Figure-1 is alongitudinal vertical section of a T or connection-pipe with myimprovement attached;

Figure 2 is a front view of the same; and

Figure 3 is a longitudinal vertical section of the end of a stove-pipe,of my construction, that goes into the chimney. V

A represents the end of a stove-pipe that is inserted into achimney-flue, B.

The end of this pipe is closed, being of the inclined or slanting shapeshown in fig. 3, so that the upper edge of the pipe enters farther intothe flue than the lower.

At the upper inner edge, the stove-pipe A is cut open, as shown in thatfigure, leaving the end-plate O proj ccting upward.

When the smoke, 860., from the stove, passes through thepipe, if stikesthe inclined end-plate O,which changes its direction from horizontal toperpendicular, when it passes up into the chimney through the opening D.

It will be seen that the currents from the stove-pipe A, and from theflue B, when they strike each other. are going in the same direction.

In a T or connection-pipe, as represented in figs. .i' and 2, I attach,in the main pipe E, a curved plate, F, opposite to the end of the sidepipe G.

The plate F is so placed that the curved part thereof extends below thelower edge of the side pipe, and the plate extends far enough up toallow the current from the side pipe to change before it strikes thecurrent from the main pipe, the two currents, at the point and time ofjoining, moving in the same direction.

I do not confine myself to any particular mode or manner of attachingthe plate F, as that may be done in any manner desired. r

' By this improvement I give every stove a separate draught, clearthrough the building, even if of con siderable height, as perfect adraught as a stove would have in a one-story building, preventing theinterference of the draught from one stove with that from the other, or,rather, the draught from the stoves above interfering with the draughtof the stoves in the stories below, giving a perfect draught to thefines, also to-the stove-pipes throughout the building.

f In the drawings'I haveonly shown my method of changing a horizontalcurrent to a perpendicular, but it is clear that a perpendicular currentmay, in like manner, be changed to a horizontal.

Having thus fully described my invention,

What I claim as new, and desire to secure by Let ers Patent, is

1. Oonvertin g the horizontal draught of a stove-pipe into aperpendicular, or a perpendicular draught into a horizontal,substantially as and for the purposes herein set forth. I

2. Constructing the end of a stove-pipe, where it joins the chimney-flueor main pipe, in, such a manner that the current from said stove-pipemay be changed, and the two currents, at the time when they join eachother, may be moving in the same direction, substa'ntially as herein setforth.

In testimony that I claim the foregoing, I have hereunto set my hand,this 9th day of January, 1869.
